Merchants of Hatred: On the anniversary of 9/11 this terrifying investigation reveals the hatred of Britain's enemies within

Sheikh Omar Bakri Mohammed says this country will soon become a Muslim state ruled according to the Koran

Their message was as disturbing as ever - and the date, September 11, was particularly symbolic.

On Thursday evening this week, at a packed meeting in London's East End, two profoundly dangerous men urged the destruction of the British way of life.

I was there as the radical cleric and self-styled sheikh Omar Bakri Mohammed proclaimed that this country - where he received state benefits for two decades - will soon be transformed into an Islamic state, or Khilafah, run according to the rules of the Muslim holy book, the Koran.

Bakri's black-robed right-hand man went one step further. Anjem Choudary, a 41-year-old militant and the leading light of a thriving new organisation called islam4UK declared: 'There are already six or seven million Muslims here in Britain.

'By the year 2020, we will be the majority.

'In the streets of London - Whitechapel, Bethnal Green, Stratford - people are becoming Muslim in their droves. By sheer numbers, Britain will become an Islamic state.

'We will never need to conquer this country. Our eyes are now on Downing Street,' he added, with an excited laugh.
